Cityscape: Behind the Mask

For most of us, masks come out once or twice a year -- during Halloween or costume parties. But, for some, putting on a mask is a daily occurrence.

A mask is a barrier between ourselves and the world. It conceals our identity and can free us in some way from our societal restrictions. Think about how liberated people sometimes feel on Halloween.

On this week's Cityscape, we’re talking about masks, and our fascination with them. We'll look at how masks are created and used in performance, as well as why some people wear metaphorical masks every day to protect themselves.
